Hao Zhu created DRILL-3336:
------------------------------

             Summary: to_date(to_timestamp) with group-by in hbase/maprdb table fails with
"java.lang.UnsupportedOperationException"
                 Key: DRILL-3336
                 URL: https://issues.apache.org/jira/browse/DRILL-3336
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow, Functions - Drill
    Affects Versions: 1.0.0
         Environment: 1.0 GA version
            Reporter: Hao Zhu
            Assignee: Chris Westin
            Priority: Critical


1. Create a hbase/maprdb table in hbase shell:
{code}
create '/tables/esr52','cf'
put '/tables/esr52','1434998909','cf:c','abc'
> scan '/tables/esr52'
ROW                                                                  COLUMN+CELL
 1434998909                                                          column=cf:c, timestamp=1434998994785,
value=abc
{code}

2. Below SQLs work fine in Drill:
{code}
>  select * from maprdb.esr52;
+--------------+---------------+
|   row_key    |      cf       |
+--------------+---------------+
| [B@5bafd971  | {"c":"YWJj"}  |
+--------------+---------------+
1 row selected (0.095 seconds)

> select to_date(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int))) from
maprdb.esr52 esrtable;
+-------------+
|   EXPR$0    |
+-------------+
| 2015-06-22  |
+-------------+
1 row selected (0.127 seconds)
{code}

3. However below SQL with group-by fails:
{code}
select to_date(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int))),count(*)
from maprdb.esr52 esrtable 
group by to_date(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)));

runtime code generation expected.  Signature: compare_to_nulls_high( VAR16CHAR:OPTIONAL, VAR16CHAR:OPTIONAL
) returns INT:REQUIRED

{code}

4. If we remove to_date, and only group-by to_timestamp, it works fine:
{code}
select to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)) from maprdb.esr52
esrtable;
+------------------------+
|         EXPR$0         |
+------------------------+
| 2015-06-22 18:48:29.0  |
+------------------------+
1 row selected (0.084 seconds)

select to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)),count(*) from maprdb.esr52
esrtable
group by to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int));
+------------------------+---------+
|         EXPR$0         | EXPR$1  |
+------------------------+---------+
| 2015-06-22 18:48:29.0  | 1       |
+------------------------+---------+
1 row selected (0.641 seconds)
{code}

As a workaround, we can use substr instead of to_date.
{code}
select substr(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)),1,10) from
maprdb.esr52 esrtable;
+-------------+
|   EXPR$0    |
+-------------+
| 2015-06-22  |
+-------------+
1 row selected (0.132 seconds)

select substr(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)),1,10),count(*)
from maprdb.esr52 esrtable
group by substr(to_timestamp(cast(convert_from(esrtable.row_key,'UTF8') as int)),1,10);
+-------------+---------+
|   EXPR$0    | EXPR$1  |
+-------------+---------+
| 2015-06-22  | 1       |
+-------------+---------+
1 row selected (0.678 seconds)
{code}

Need fix.
